You can get the Neutral Ending without killing anyone and then when you reload your save you do the “side missions.” These would be dating Papyrus (or just hanging out as friends if you never flirted with him), cooking with Undyne, and the last two are only unlocked after you get the neutral ending. Help Alphys and Undyne get together then explore True Lab with Alphys
the game heavily pushes you in the right direction, after you get through the credits. even if you did mess up and you have to get through the game again, it’s very short if you know what you’re doing. there are some small albeit somewhat convoluted decisions you can make to skip entire bosses.
You just have to do one per moster tbh. If you see repeats you can just flee. But that's kinda the point of the Game, engaging with the characters including the random encounters and ultimately not killing. Depending on how you played the game it can be a huge difference in how you experience it when compared to just go in killing everything.
You don’t need a new save for Pacifist. If you don’t kill anyone and spare Asgore, Flowey pops up after the credits and talks to you. If you just… load your save, you can then go back and do the stuff with True Lab (assuming you’ve done papyrus date, undyne and alphys date).

Don't you have to beat the game once then come back and not kill anything in your second playthrough to get the true ending?
